【発明の属する技術分野】

【０００２】
【従来の技術】
従来、この種の積層熱交換器としては、例えば、図１３に示すものがある。図１３は、従来の積層熱交換器の構成図であり、１はステンレス等の金属性の積層板で、積層板２を重ねて１次側流体流路３を構成し、積層板２の上に積層板４を重ねて２次側流体流路５を構成し、順次積層板を重ねて１次側流体流路と２次側流体流路を交互に形成し、積層板外周をロー付けしてシールして積層熱交換器を構成している（例えば、特許文献１参照）。

【０００４】
【発明が解決しようとする課題】
しかしながら、前記従来の構成では、ステンレス等の金属板をプレス加工して伝熱体を作成し、伝熱体そのものを積層板として積層してロー付けして流体流路を形成して用いていたため、伝熱体を構造体として用いることにより、伝熱体の厚みが厚くなり、熱抵抗が大きくなって熱交換性能が低くなり、積層枚数も多くなって装置が大きくなるという課題を有していた。さらに積層板の接合のためには真空炉などの高価なロー付け設備が必要であり製品コストも過大になる等の課題を有していた。
【０００５】
本発明は、前記従来の課題を解決するもので、構造体として強度を有する枠板と厚みが薄く熱抵抗の小さい伝熱板に分離して構成することにより小型高性能でシール性に優れた安価な積層熱交換器を提供することを目的とする。
【０００６】
【課題を解決するための手段】
前記従来の課題を解決するために、本発明の積層熱交換器は、１次側流体の流路を形成し両面に凸状外周シール材を有する１次側枠板と伝熱体と２次側流体の流路を形成し両面に平板状外周シール材を有する２次側枠板とを順に積層したものである。
【０００７】
これによって、枠板で構造強度を保証することができ、一方で伝熱体を薄くすることにより熱抵抗を小さくすることができる。また、薄い伝熱体を凸状外周シール材と平板状外周シール材ではさむことにより信頼性の高いシールが実現できる。
【０００８】

【００２０】
【実施例】
以下、本発明の実施例について、図面を参照しながら説明する。
【００２１】
（実施例１）
図１（ａ）は、本実施例の第１の実施例における積層熱交換器の構成図、図１（ｂ）は、その分解図を示すものである。
【００２２】
図１において、６は１次側枠板で、１次側流体流路３を形成する枠板開口部７と、１次側流体が通り分流路８ａを有する２個の流路穴９ａと、２次側流体が通る２個の流路穴９ｂと、両面に凸状外周シール材１０とを有する。１１は２次側枠板で、２次側流路５を形成する枠板開口部と、２次側流体が通り分流路８ｂを有する２個の流路穴９ａと、１次側流体が通る２個の流路穴９ｂと、両面に平板状外周シール材１２を有する。１３は、分流路８のない流路穴９ｂの周囲に設けたＯリングである。１４は、１次側枠板６と伝熱体１５と２次側枠板１１とを１次側枠板６が両端にくるように順に複数枚積層した積層ブロックで、両端に前端板１６と後端板１７とを設けて締結材１８で締結して加圧保持している。
【００２３】
以上のように構成された積層熱交換器について、以下その動作、作用を説明する。
【００２４】
まず、１次側流体は、１次側枠板６の流路穴９ａから分流路８ａを通って１次側流路３を流れる。一方、隣接する２次側枠板１１の２次側流体は流路穴９ｂから分流路８ｂを通って２次側流路５を流れる。１次側流体と２次側流体とは伝熱体１５を介して接しているので、両流体間で熱を移動することができる。また１次側流路３と２次側流路５の高さは、１次側枠板６と２次側枠板１１の厚みを設定することにより伝熱板１５の厚みに関係なく任意に設定することができる。
【００２５】
以上のように、本実施例においては伝熱板１５を１次側枠板６と２次側枠板１１と分離した構成とすることにより、１次側枠板６と２次側枠板１１で強固な構成をつくり伝熱板１５の厚みを薄くすることによって、高圧の流体を大量に流すことができ大量の熱を移動することができる。さらに伝熱板１５は外周においては１次側枠板６の凸状外周シール材１０と２次側枠板１１の平板状外周シール材１２によって挟まれた構成となっているため伝熱板１５が多少変形しても確実にシールすることができる。
【００２６】
（実施例２）
図２（ａ）は、本発明の第２の実施例の積層熱交換器の１次側枠板の構成図、図２（ｂ）は、２次側枠板の構成図である。
【００２７】
図２において、１９はリング状シール材で、実施例１の構成と異なるところは、リング状シール材１９を流路穴９ｂの周囲に設けた段差２０に嵌め込んで１次側枠板６および２次側枠板１１を挟み込んで設けた点である。
【００２８】
以上のように構成された積層熱交換器について、以下その動作、作用を説明する。
【００２９】
まず、ゴムなどの弾性体で作られたリング状シール材１９は１次側枠板６と２次側枠板１１の段差２０に嵌め込んで流路穴９ｂに設ける。
【００３０】
以上のように、本実施例においては１個の部品で流路穴９ｂの両面を確実にシールすることができるので、作業性に優れ信頼性の高いシールを実現することができる。
【００３１】
（実施例３）
図３は、本発明の第３の実施例の積層熱交換器の構成図である。
【００３２】
図３において、２０はフィルム状薄膜で、実施例１の構成と異なるところは伝熱板１５としてフィルム状薄膜２０を設けた点である。
【００３３】
以上のように構成された積層熱交換器について、以下その動作、作用を説明する。
【００３４】
まず、１次側枠板６の１次側流体流路３を流れる１次側流体と２次側枠板１１の２次側流体流路５を流れる２次側流体とはフィルム状薄膜２０によって分離されている。
【００３５】
以上のように、本実施例においては１次側流体と２次側流体とをフィルム状薄膜２０によって分離することにより、１次側流体から２次側流体に熱を伝える時に伝熱体の厚さを極めて薄くする事ができるので熱抵抗が小さくなり大量の熱を移動する事ができる。
【００３６】
また、本実施例では、フィルム状薄膜２０の両側を凸状外周シール材１０と平板状外周シール材１２によって挟む構成としたことにより、しわ等が生じ易いフィルム状薄膜２０を伝熱体として用いても確実にシールすることができる。
【００３７】
また、本実施例のフィルム状薄膜２０に多孔質または電解質などの透湿性の膜を用いることにより、小型高性能で流体漏れの少ない組み立て性に優れた安価な全熱交換器または加湿器を実現することができる。
【００３８】
（実施例４）
図４（ａ）は、本発明の第４の実施例の積層熱交換器の構成図、図４（ｂ）は、その構成部品であるフィルム状薄膜、図４（ｃ）は、保持板の構成図である。
【００３９】
図４において、２１は中央部に複数の開口部２２と流体が通過する４個の流路穴９を有する保持板で、実施例３の構成と異なるところは、フィルム状薄膜２０に密着して保持板２１を設けた点である。
【００４０】
以上のように構成された積層熱交換器について、以下その動作、作用を説明する。
【００４１】
まず、１次側流路３を流れる１次側流体が２次側流路５流れる２次側流体より圧力が高い場合、フィルム状薄膜２０は１次側枠板６内の１次側流体に押されて２次側流体が流れる２次側枠板１１の２次側流路５を閉塞する方向に変形するが、この時、保持板２１がフィルム状薄膜２０に密着して設けられているため変形を防止することができる。一方、保持板２１には、複数の開口部２２が設けられているのでフィルム状薄膜２０を通して１次側流体から２次側流体に熱を移動する事ができる。
【００４２】
以上のように、本実施例においてはフィルム状薄膜２０に密着して保持板２１を設けることにより、１次側流体と２次側流体の圧力が異なる場合においても流体の流路を閉塞することなく安定した運転を維持することができる。
【００４３】
（実施例５）

【００４４】
図５において、１５は伝熱体で、実施例４の構成と異なるところは、開口部２２を有する銅またはアルミ、ステンレス等の金属製薄板からなる２枚の熱伝導性保持板ｂ２１の間に熱伝導性保持板ｂ２１の１００分の１以下の厚みのフィルム状の薄膜２０をロールプレスなどで密着接合して設けた点である。
【００４５】
以上のように構成された積層熱交換器について、以下その動作、作用を説明する。
【００４６】
まず、１次側流路３を流れる１次側流体が２次側流路５を流れる２次側流体より著しく圧力が高い場合、伝熱体１５は１次側流体に押されて２次側流体が流れる２次側流路５を閉塞する方向に変形するが、この時、伝熱体１５はフィルム状薄膜２０の両面に熱伝導性保持板ｂ２１を設けた構成としたため、伝熱体１５の変形を微少に留める事ができる。一方、運転状態が変化して１次側流体と２次側流体の圧力が逆転して２次側流体の圧力が高くなった場合、伝熱体１５は２次側流体に押されて１次側流体が流れる１次側流路３を閉塞する方向に変形するが、この時も、フィルム状薄膜２０の両面に熱伝導性保持板ｂ２１を設けているため、伝熱体１５の変形を微少に留める事ができる。
【００４７】
以上のように、本実施例においてはフィルム状薄膜２０の両面に熱伝導性保持板ｂ２１を設けることにより、１次側流体と２次側流体の圧力差が著しくことなる場合また運転途中で圧力差が逆転する場合でも流路を閉塞することなく安定して運転することができる。
【００４８】
また、保持板として開口部２２を有する熱伝導性保持板ｂ２１を用いているため、開口部２２のフィルム状薄膜２０だけでなく熱伝導性保持板ｂ２１を介しても熱を移動することができるので、１次流体から２次流体へ大量の熱を移動することができる。
【００４９】
（実施例６）

図６において、２３は２次側流路５内に設けた複数の変形防止スペーサで、実施例４の構成と異なるところは、２次側流路５の両側に設けた保持板２１に開口部２２を避けて密着して変形防止スペーサ２３を設けた点である。
【００５１】
以上のように構成された積層熱交換器について、以下その動作、作用を説明する。
【００５２】
まず、１次側流路３を流れる１次側流体が２次側流路５を流れる２次側流体より著しく圧力が高い場合、保持板２１は１次側流体に押されて２次側流体が流れる２次側流路５を閉塞する方向に変形するが、この時、保持板２１の間に変形防止スペーサ２３を設けているため保持板２１が変形して２次側流路５を閉塞することを防止する事ができる。
【００５３】
以上のように、本実施例においては２次側流路５内に変形防止スペーサ２３を設けることにより、１次側流体と２次側流体の圧力差が著しくことなる場合でも流路を閉塞することなく安定して運転することができる。
【００５４】

【００５６】
以上のように構成された積層熱交換器について、以下その動作、作用を説明する。
【００５７】
まず、１次側流路３を流れる１次側流体が２次側流路５を流れる２次側流体より著しく圧力が高い場合、保持板２１は１次側流体に押されて２次側流体が流れる２次側流路５を閉塞する方向に変形するが、この時、保持板２１の凸状突起２４が対向する保持板２１に接することにより、フィルム状薄膜２０と保持板２１が著しく変形するのを防止することができる。
【００５８】
以上のように、本実施例においては保持板２１に複数の凸状突起２４を設けることにより、保持板２１の変形を防止することとなり、１次側流体と２次側流体の圧力差が著しく大きい場合でも、部品を追加することなく２次側流路５の閉塞を防止して安定した運転を維持することができる。
【００５９】
（実施例８）
図８（ａ）は、本発明の第８の実施例の積層熱交換器の構成図、図８（ｂ）は、その構成部品である２次側枠板の構成図である。
【００６０】
図８において、２５は伝熱体保持部、２６は変形防止部で、実施例１から７の構成と異なるところは１次側枠板６と２次側枠板１１の少なくとも１方の片面または両面に伝熱体保持部２５と変形防止部２６を一体に設けた点である。
【００６１】

【００６３】
以上のように、本実施例においては伝熱体保持部２５と変形防止部２６とを２次側枠板１１の一部として成型加工時に同時に成形することにより部品点数を大幅に削減することができる。
【００６４】
（実施例９）

【００７４】
以上のように、本実施例においては２次側枠板１１の端部の両面に設けた接着用段落とし部２９に接着材３０を設けて２次側枠板１１に伝熱体１５を強固に固定することにより、１次側枠板６と２次側枠板１１を積層する時に伝熱体１５が所定の位置からずれて生じるシール不良を防止することができる。さらに、接着用段落とし部２９を設けたことにより接着部の厚みを２次側枠板１１の厚み以下に設定することができるので、凸状外周シール材１０と平板状外周シール材１２の圧縮率を低下させることなく枠板を積層する事ができるので、確実で信頼性の高いシールを実現することができる。さらに接着材３０は平板状外周シール材１２の外側に設けられているため２次側流体と接触することが無く接着材３０の成分が流体に溶出して燃料電池等の他の構成機器に悪影響をおよぼすことを防止することができる。
【００７５】
